got a great deal on this monitor with a price match. but might need to return it. the display port works fine, but running hdmi output from a capture card from a second pc back into this monitor displays a "no signal" message. if i plug the hdmi directly into the monitor from my gpu i get a signal. is this issue indigenous to display port monitors? no issues doing this with my dvi/hdmi monitors i'm currently using. thanks. ps. i realize my capture card is not compatible via display port, but i figured hdmi in 1080p would work.
